Abstract

Embodiments of the present disclosure are directed to conserving energy of an injection device that includes an energy source, an electronic component configured to be electrically decoupled from the energy source, a priming component configured to generate a trigger, and a mechanism attached to the priming component and configured to perform operations comprising in response to receiving the trigger, electrically coupling the energy source to the electronic component.

First claim

1 - 15 . (canceled)

16 . An injection device comprising:
an energy source;
an electronic component configured to be electrically decoupled from the energy source;
a priming component configured to generate a trigger; and
a mechanism attached to the priming component and configured to perform operations comprising in response to receiving the trigger, electrically coupling the energy source to the electronic component.

17 . The injection device of claim 16 , wherein the mechanism comprises a switch configured to be activated for electrically coupling the energy source to the electronic component.

18 . The injection device of claim 16 , wherein the energy source is configured to be moveable between two positions.

19 . The injection device of claim 18 , wherein the mechanism is configured to couple the energy source to the electronic component by moving the energy source from a first position, in which the energy source is electrically decoupled from the electronic component to a second position, in which the energy source is electrically coupled with the electronic component.

20 . The injection device of claim 16 , wherein the electronic component comprises two contact plates.

21 . The injection device of claim 20 , wherein the energy source comprises two pins configured to couple with the two contact plates.

22 . The injection device of claim 16 , wherein the electronic component is included in a plunger stopper.

23 . The injection device of claim 16 , wherein the energy source is attached to at least one of a bearing, a plunger rod, and a cavity in a plunger head.

24 . The injection device of claim 21 , wherein the electronic component is included in a plunger stopper and the two pins are configured to pierce at least a portion of the plunger stopper for electrically coupling with the electronic component.

25 . The injection device of claim 23 , wherein the energy source is attached to a plunger rod separated from the bearing by an electrically insulating membrane and configured to move in a distal direction during priming and dispense of a medicament.

26 . The injection device of claim 21 , wherein the two pins are configured to pierce the electrically insulating membrane for electrically coupling with the electronic component.

27 . The injection device of claim 16 , comprising a support configured to attach the energy source to a component of the injection device.

28 . The injection device of claim 27 , wherein the support comprises a shape configured to transmit a dispensing force from the priming component to electrically couple the energy source to the electronic component.

29 . The injection device of claim 16 , comprising a medicament reservoir comprising a medicament.

30 . A medicament injection system comprising:
an injection device comprising: an energy source, an electronic component configured to be electrically decoupled from the energy source, a priming component configured to generate a trigger, and a mechanism attached to the priming component and configured to performing operations comprising in response to receiving the trigger, electrically coupling the energy source to the electronic component; and an external processor configured to communicate with the electronic component.

31 . The medicament injection system of claim 30 , wherein the electronic component comprises an antenna configured to transmit an electric signal to the external processor.

32 . The medicament injection system of claim 31 , wherein the external processor is configured to perform operations comprising: receiving a user input indicating that a medicament is to be expelled by the injection device; and transmitting to the priming component of the injection device a signal to generate the trigger.

33 . The medicament injection system of claim 32 , wherein the antenna is configured to transmit an amount of the medicament to be expelled.

34 . The medicament injection system of claim 30 , further comprising a support configured to attach the energy source to a component of the injection device.

35 . The medicament injection system of claim 34 , wherein the support comprises a shape configured to transmit a dispensing force from the priming component to electrically couple the energy source to the electronic component.
